Answer:A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Write and solve an equation to find the length of each side of the triangle.
The sides can be found by taking the square root of the area. , where = side. . So the length of a side is 6.3 cm.
Step-by-step explanation:
The circumference is the correct.
It can be found using the formula,
Answer:
Dimensions of the original rectangle:
Length = 19 cm
Width = 11 cm
Step-by-step explanation:
Let
Length = x
Width = y
Original rectangle:
2(Length + width) = 60
2x + 2y = 60
New rectangle has same length with original rectangle but half of the width of the original rectangle when folded
Length = x
Width = 1/2y
2(Length + 1/2width) = 49
2x + y = 49
2x + 2y = 60 (1)
2x + y = 49 (2)
Subtract (2) from (1) to eliminate x
2y - y = 60 - 49
y = 11
Substitute y = 11 into (2)
2x + y = 49
2x + 11 = 49
2x = 49 - 11
2x = 38
x = 38/2
x = 19
Dimensions of the original rectangle:
Length = 19 cm
Width = 11 cm
Just choose x = 0,1,2,3 and find y for each x, for each of the tables.
Solving as fractions, the amount of feet from each side of the wall would be: 4⅛ feet.
<h3>Solving Fractions</h3>
Given the following:
- length of the wall = 10¾ feet
- length of the picture = 2½ feet
Therefore:
Amount of feet from each side of the wall = [10¾ - 2½]/2
= [43/4 - 5/2]/2
= [(43 - 10)/4]/2
= 33/4 × 1/2
= 33/8
= 4⅛ feet
Therefore, solving as fractions, the amount of feet from each side of the wall would be: 4⅛ feet.
